Professor Shankar was very bad at teaching, his lectures made little to no sense most of the time, and sometimes he would have entire lectures where he would go off on a tangent. His exams are way harder than the homework, and he does not care about his class","source_url":"https://www.ratemyprofessors.com/professor/2870666","quality_rating":1.0,"difficulty_rating":4.0},{"observed_at":"2026-09-07 16:51:37.641601+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTQyNTIzODM5","source_instructor_id":"rmp:2279567","instructor_name":"Botong Wang","course_label":"MATH467","course_id":"MATH 467","course_uid":"course_e7b7ff33c37b147a17b2d14d","review_date":"2026-01-20 17:39:10 +0000 UTC","comment":"Manages to break down advanced concepts very well. Motivates almost everything with examples. The homework directly prepares you for the exams which are very straight forward.

I expected him to teach us several competition style techniques, but the truth is that you can tell that he is way too busy for his research.

He cares about his students and the subject and his passion rubs off on you. Exams were extremely fair and he gave specific practice problems so you knew what to expect. Funny, caring, responsive to emails and in office hours, the list goes on. Take a class with this guy if you can!!","source_url":"https://www.ratemyprofessors.com/professor/1852275","quality_rating":5.0,"difficulty_rating":3.0},{"observed_at":"2026-09-07 16:17:02.037647+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTM4NjQxMTEz","source_instructor_id":"rmp:2680569","instructor_name":"Mikhail Ivanov","course_label":"Math467","course_id":"MATH 467","course_uid":"course_e7b7ff33c37b147a17b2d14d","review_date":"2023-12-13 02:19:34 +0000 UTC","comment":"He's an excellent professor. He makes the material very clear, and follows the textbook's pacing+instructions. He was very clear with explanations at office hours. I will be taking a class with him next semester. I think a lot of the negative reviews are from people who are taking a hard math class for the first time.
